multi-layer boards and European pine boards have only been used for walls, floors and roof sheathing since the 1970s. Why are they now so widely used in whole-house customization?
as they all replace solid wood which is increasingly expensive and scarce. Why are they made from cheap, fast-growing pine eucalyptus but perform just as well as solid wood? Because they all have their own unique arrangement and bonding technology. Multi-layer boards are made of veneers cut into pieces from logs and then cross-glued together. In order to ensure the sturdiness of the cross-grain, multi-layer boards are made of odd-numbered layers such as 3, 5, and 7 layers. However, if there are scars and cracks on the board, it will be very obvious. Therefore, when making furniture, we generally purchase first-grade boards to ensure a smooth and flawless surface.
What is the European pine board like? The logs are cut into wood chips by machine. The long wood chips on the surface face one direction and the short wood chips in the middle face the other direction. They are pressed with glue by the press . OSB does not have scars or holes like multi-layer boards, any surface is uniform, and the arrangement and bonding of the wood chips makes it very strong. There are generally 4 uses for OSB board, the best is used for load-bearing, the worst is used for packaging and furniture, and the most commonly used is used for decoration.
Multi-layer boards leave less sawdust when cutting, while European pine boards are more likely to chip when cut, but they both hold nails quite well. Multi-layer boards are better waterproof than European pine boards, so they are generally used to make bathroom cabinets . In terms of fire protection, even if the multi-layer board is scorched, the fire does not spread, while the OSB board is scorched faster, but they are both fire-resistant. In terms of environmental protection, both European pine boards and multi-layer boards can be formaldehyde-free, because current glues use urea-formaldehyde resin (UF) and isocyanate (MDI). In terms of sustainability, European pine boards save more wood than multi-layer boards because their wood chips are easier to obtain and have a high utilization rate. Although the production line of European pine board is very expensive, it does not have as many steps as the production of multi-layer boards, so its price is also more favorable than that of multi-layer boards. Currently, the price of full pine E0 European pine board starts at 65 yuan per piece.
Generally speaking, these two boards are the innovative crystallization of people's material saving, so they are currently the most popular boards.
